A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and the analog and digital sections should be separated to minimize noise coupling.
The clocking scheme should be optimized to minimize jitter and ensure proper synchronization. A low-jitter clock source, such as a crystal oscillator, should be used, and the clock signal should be routed close to the device to minimize noise.
The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the clock signal. This ensures that the device powers up correctly and minimizes the risk of latch-up.
The device should be mounted on a heat sink or a thermal pad to dissipate heat. The PCB should be designed to allow for good airflow, and thermal vias can be used to dissipate heat from the device to the PCB.
The recommended filter configuration depends on the specific application, but a 5th-order Butterworth filter or a 7th-order elliptical filter are commonly used. The filter should be designed to minimize group delay and ensure a flat frequency response.
